Debian 資助 PeerTube 發展

看到「Debian donation for Peertube development」這則消息，Debian 決定資助 10K 歐元提供給 PeerTube 發展。

不過更大的幫助應該是 PR 上的部份，這帶出來的曝光度以及「認可」的部份比 10K 歐元重要的多。

回到 Debian 決定資助的原因，是因為 DebConf20 需要一個非封閉式平台的直播架構，而 PeerTube 看起來很適合這個情境：

This year’s iteration of the Debian annual conference, DebConf20, had to be held online, and while being a resounding success, it made clear to the project our need to have a permanent live…

DebConf20 Debian Conference começa hoje com foco no Debian 11 Bullseye

A DebConf20 Debian Conference começa hoje e vai até 29 de agosto com foco no lançamento do Debian GNU/Linux 11 Bullseye. Em tempos de coronavírus esta é a primeira conferência on-line do Projeto Debian. Este ano, o Projeto Debian celebra dois grandes eventos, o 27º aniversário do projeto e 12 anos desde o lançamento da primeira conferência de desenvolvedores Debian DebConf.

Um encontro anual,…

Setup debconf frontend

By default debconf uses ‘dialog’ interactive frontend so in case there are options to choose from during package installation a relevant dialog with a list of available options will pop up. Even if apt is used with -y (--assume-yes) option it still may require some user input. To completely disable this behavior and make the dpkg backend always choose the default options (i.e. in non interactive scripts) set the debconf frontend to ‘noninteractive’ by exporting relevant environment variable:

export DEBIAN_FRONTEND=noninteractive

Reconfigure default editor

sudo update-alternatives --config editor

Persisting netfilter firewall rules across boots in Ubuntu Xenial

Install iptables-persistent package.

Rules (IPv4) to be applied are held in /etc/iptables/rules.v4 file. Dump current rules to it:

iptables-save > /etc/iptables/rules.v4

Rules management is done by a native systemd service named netfilter-persistent:

#Enable rules at boot: systemctl enable netfilter-persistent #Load rules manually systemctl start netfilter-persistent #Clean all rules /usr/sbin/netfilter-persistent flush

Listing all available package versions

“--showduplicates“ option of yum’s “list” command shows all available versions for a given package:

How-to: automate dpkg-reconfigure tzdata #computers #programming #fix

automate dpkg-reconfigure tzdata

I’m using puppet to admin a cluster of debian servers. I need to change the timezone of each machine on the cluster. The proper debian way to do this is to use dpkg-reconfigure tzdata. But I can only seem to change it if I use the dialog. Is there some way to automate this from the shell so I can just write an Exec to make this easy?

If not, I think the next best…
